Overview
The J2 625 is a new generation of integrated touch screen Point of Sale computer based
on the Intel Atom dual core Cedarview processors. This integrated touch screen
computer, like other J2 designs, features an “all-in-the-head” design, and it also offers the
versatility to be used as a counter top unit; or as a wall-mount or pole-mounted terminal.
Using the same J2 packaging design as other J2 products the J2 625 offers same features
the very successful J2 615 but with newer faster electronics and easier service and the
same price point.
The J2 625 uses the latest Intel Atom dual core Cedarview processors, the 1.86GHz
D2550. Combining this with the Intel NM10 chipset provides excellent performance
capable of running most POS applications with a very low carbon foot print, all at a
competitive and attractive low price.
Even with its small foot print the J2 625 is incredibly feature rich. It comes standard with
2GB of memory, and offers a choice of either a 160GB hard drive or 16GB solid state
drive (or other capacities HDD/SSD). Built standard with four serial ports, six USB ports,
video output, audio in/out, gigabit Ethernet, +12V output, as well as other built in
peripherals (like MSR, customer display and more) the J2 625 will perfectly satisfy most
POS application requirements.
The J2 625 is available with your choice of either a zero bezel resistive touch screen or a
multi-touch projected capacitive touch screen. The new zero bezel five-wire resistive
touch screen provides the same quick response and feel of a resistive touch screen
traditionally used in the POS market. The new projective capacitive touch screen option
can be used in environments where multi-touch and gesturing are required, for example,
such as when using the new Windows 8 operating system.
The J2 625 is designed to require little or no maintenance. The convection cooled fan-less
design means it can be used in very harsh environments. High dust, grease or sea air will
not affect its operation. High temperatures are also not a problem. With a quick access
HDD/SDD slot, a drive can be changed in just seconds if needed. The unit can be fully
disassembled and assembled in just a few minutes by just removing a few screws.
The J2 625 supports the standard Microsoft operating systems: Windows 7, POSReady 7,
Windows 7 Embedded, XP, POSReady 2009 and XP embedded, as well as the soon-to-
be-released Windows 8. The J2 625 is equally proficient with the many flavors of Linux.

J2 625 Integrated Touch Screen Computer
I/O Ports
Most I/O ports are accessible in the cable well at the bottom of the unit. Cables are routed
though the cable channel in the swing arm base. (See Cable Routing)
I/O Panel
Off / On Button
The Off /On button is located in the cable well, as shown below. This button is located
near the side to prevent accidental powering down by the user. The function of the button
can be controlled by the OS. If the J2 625 hangs for some reason it can always be
powered off by holding the Off /On button in for six seconds.
The J2 625 also supports the following: Restore on AC on power loss, Wake On LAN,
and Wake On RTC alarm features to control the system power up. The setting for these
features is controlled from the BIOS.
Off / On Button Location
Hard Disks
One 2.5 inch SATA hard drive (HDD) or a solid state drive (SSD) are standard with the
J2 625. The SATA interface can support data transfer rates up to 3.0 GB/s. The J2 625
offers standard either a 160GB HDD or 16GB SSD, but can be ordered with other size
HDD or SSD as well. See J2 for details.

The HDDs can easily be accessed by removing a panel on the left side of the unit. HDDs
can be installed or removed in seconds by removing one screw. A carrying tray fits onto
a drive without tools. The drive can now easily be slid in or out of the drive bay using the
pull tab on the drive dray.
HDD access panel
HDD slide in-slide out drive bay
Touch Screen
The J2 625 can be ordered with two different touch screen technologies, PCT or TFR.
The PCT unit uses a multi-touch Projected Capacitive Technology touch screen. The PCT
touch screen has no known failure mode-- it does not “wear out.” This screen is
tempered glass and does not reduce the brightness of the J2 625 panel. When operating
in a very high use environment, the PCT is the recommended touch screen technology.
The PCT touch screen will work with most gloves and stylus that are designed to work
with tablet computers, and the screen has a smooth glass surface that is reflective.
The TFR uses a five-wire true flat (zero bezel) resistive touch screen rated at 35 million
touches per point. The resistive technology is very responsive and is the traditional choice
for a hospitality POS system. The screen has an anti-reflective plastic film surface.
Both screens are fully spill proof, dust proof, and can be cleaned with a standard glass
cleaner. The J2 625 touch screen was designed to easily be changed, normally in less than
two minutes. Depending on operating environment and usage, both the Resistive and
PCT touch screens have strengths and weaknesses; therefore J2 offers both touch screen
technologies on the J2 625 unit, providing our customers with a choice for any
application requirement.

System Board
POS computers typically have a lifespan of 10 years or longer, therefore product quality
is of the utmost importance. J2 625 electronics are built with high-end components to
ensure reliability and long lasting product performance.
The system board is designed for quick replacement, with just a few screws and cables to
unplug. The board can be swapped out in less than three minutes.
J2 625 System board
J2 625 Display
The J2 625 offers 15 inch 1024 x 768 resolution display with 16.2 Million colors, CCFL
backlight with 4:3 aspect ratio screen. The brightness is rated at 250cd/m2. The Intel
controller allows for the display to be rotated to 0, 90, 180 or 270 degrees without loss of
performance. The driver can also scale the display resolution so that it can work properly
with applications written for 800x600 resolutions.
The J2 625 electronics also supports dimming, and can be controlled directly by
Windows 7 or 8, or with J2 supplied utilities for Windows XP. Dimming levels between
10-100% are supported. A hardware auto dimming feature is built-in to ensure the longest
backlight life and to also provide the lowest power usage.

Secondary Video Port
The J2 625 supports the newer digital video standard Display Port connector. This
connector supports a Display Port monitor, HDMI display, DVI or VGA monitor. When
used with HMDI or DVI displays, a passive adaptor cable must be used. When using a
VGA display, an active adaptor is to be used. With HDMI display Audio, support is
provided via the same HMDI cable.
The secondary video displays can be configured as Twin, Intel Dual Display Clone, or
Extended Desktop. Most all monitor resolutions from 640 x 480, up to 2560 x 1600 are
supported.
DisplayPort Video Port
Ethernet Connection
The J2 625 uses the Realtek RTL8111 Gigabit Ethernet controller. The Ethernet
connector is located in the cable well, as shown below. The Ethernet controller supports
Wake on LAN, and the BIOS supports a PXE boot ROM as well. There is a LED on the
LAN connector, this Green LED light turns on when there is LAN activity.

Serial ports
The J2 625 unit has four external RS232 serial ports, all of which can supply +12V
power. The serial ports use a ten pin RJ45 connector. The unit comes standard with four
serial cables, three 25cm (10”) RJ45 to DB9 adapter cables, and one 152cm (5’) RJ45 to
DB25 serial printer cable that works with EPSON and EPSON compatible printers.
All serial (COM) ports can be BIOS-enabled to provide +12Vpower to external devices.
This power is supplied via pin 10 of the RJ45 which corresponds to pin 9 on the DB9
adaptor. The maximum current per port is 1 amp, with a total maximum external loading
on the +12V of 3 amps.
A set of stick-on color coded labels are supplied with the cable adaptors, so that the
cables can be marked. This makes it easy to plug the cable back into the correct port,
should you need to service the unit.

Memory SODIMM(s)
The J2 625 supports two SODIMM DDR3 memory sockets. The unit comes standard
with 2GB of main memory and can support up to a maximum of 4GB. The memory type
is DDR3 800/1066.
Typical Power Consumption J2 625
The typical power consumption of the J2 625 is lower than a notebook computer and more
comparable to a netbook computer. Using the latest generation Intel’s Atom processor and
chipset allows for much lower power consumption than previous generations of POS computers.
When coupled with the proper system configuration, this can greatly reduce the system total
carbon foot print.
